This"inv'erition relates to an oil burner, the general object of the invention being to provide a simple form of burner provided with a mixing chamber into one end of which the head of an 5 adjustable nozzle extends, for introducing steam or air into the mixing chamber, with means for introducing oil into the mixing chamber, so that it will be mixed with the air or steam to provide a highly combustible mixture.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts to be hereinafter fully described, illustrated in the accompanying drawing and specifically pointed out in the appended claims.

In describing the invention in detail, reference will be had to the accompanying drawing wherein like characters denote like or corresponding parts throughout the several views, and in which:-

Figure l is an elevation of the improved burner.

Fig. 2 is a sectional view therethru.

Fig. 3 is a section on line 3-3 ofFig. 2.

In the drawing, the letter A indicates the casting which is composed ,of the elongated tubular part 1 and on the front portion of which is formed the tubular part 2 having both ends open and thispart 2 forms the mixing chamber 3. A port 4 leads. from the front end of the tubular part 1 into the chamber 3 and a pipe 5 is connected to the rear end of the-part 1 and is connected to an oil supply so thatoil will be delivered to the part 1 and will then pass therefrom through the port 4 into the front part of the chamber 3. v

A bracket 6 is formed on the rear end of the part 1 and has a threaded opening passing therethrough, the rear end of which receives the end of a pipe 'Zwhich is connected with a steam supply or an air supply. The shank 8 of the nozzle member has its rear end threaded in the bore of the part 6 and a head 9 is connected to the other end of the shank and has a tapered bore 10 therein in communication with the bore of the shank 8, the small end of this bore 10 opening out into a flaring mouth 11 at the front end of the head. The front part of the head tapers forwardly and extends into the rear end of the chamber 3, so that by adjusting the nozzle in. the bore of the bracket 6, the space between the tapered part of the head andthe rear end of the chamber 3 can be regulated so as to control the amount of air passing into the rear end of the chamber 3.

invention will be readily apparent.

"Tlie intermediate'"part of the portion llds formed with a wrench receiving enlargement 12 so that the nozzle member can be turned in the bore of the bracket 6 to adjust the same. A threaded opening 13 is formed at the front 5 end of the part 1 and aligns with the port 4 so that by removing the plug 14 which closes the opening 13, the port-can be cleaned should it become clogged. I

From the foregoing it will be seen that the device has but a few parts and is very compact and there is but one adjustment, that being the nozzle member which can be adjusted to regulate the amount of air passing into the rear end of the chamben 3 between said rear end 15 and the head of the nozzle.

This burner produces practically no soot or carbon or smoke and will not carbonize within itself. The device is mainly intended to use crude oil and the oil may be fed by gravity or 20 under pressure though the flow of the steam or air from the nozzle will produce a suction at the port 4 for drawing oil from the part 1 through the port.

The flaring mouth 11 of the nozzle head acts 25 to produce a perfect mixture of the steam or air with the oil and the mixture is discharged from the front end of the chamber 3 in a fine spray. This spray willbum completely, and

furnishes an intensely hot white flame, and 0' makes the burner practically smokeless and soot less.

It is thought from the foregoing description that the advantages and novel features of the It is to be understood that changes may be made in the construction and in the combination and arrangement of the several parts provided that such changes fall within the scope of the appended claims. 40 Having thus described my invention, what I claim as new is: v

1. A burner of the class described comprising a casting having an elongated chamber in its upper part and a tubular part depending from the front portion of said upper part, said tubuits rear end threaded in said passage with a I nozzle head on its front end projecting into the rear end of the mixing chamber, with said head spaced from the ,wall of the'rear end of the mixing chamber, to form an air-opening, that portion of the casting between the mixing chamher and the first mentioned chamber having a port therein placing the first chamber in communication with the mixing chamber, a pipe for introducing oil into the rear end of the first chamber anda pipe threaded into the rear end of the passage. n theg'bracktgiorintroducing compressed fluidintothe nozzle member.'*"
